GAS HEATER.

Application filed January 16, 1922. Serial N0. 529,582.

To all whom it may concern:

Be it known that I, CONSTANT VAN SANT- voonr, a citizen of the United States, and a resident of Waukegan, in the county of Lake and State of Illinois, have invented a new and useful Improvement in Gas Heaters, of which the following is a full, clear, and exact description.

My invention relates to improvementsin gas heaters, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a gas heater in which the heated air is bypassed through a plurality of radiating pipes before it is expelled into the room.

A further object of my invention is. to provide a device of the type described in which the heated air is forced throughthe sides of the device before it is expelled therefrom. i

A further object of my invention is to provide a device of the type described in which the heated air first flows outwardly from the center thereof, then flows upwardly along the sides thereof, and then out at the rear.

A further object of my invention is to provide a device of the type described in Which the, air of the room is drawn by the heated pipes and is warmed thereby.

A further object of my invention is to provide a device of the type described which is simple in construction and which permits theheated air to become thoroughly dried before it is expelled therefrom, thus obviating any moisture from collecting on mirrors or the like.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

- My invention is illustrated in the accompanying drawing, forming part of this application, in which--- Figure 1 is a front elevation of the device,

Figure 2 is a side elevation of the device,

Figure 3 is a section along the line 33 of Figure 1, and

Figure 4 is a diagrammatic view of a portion of the device.

In carrying out my invention, I provide a casing 1 which is composed of two side members 2 and 3. The side members 2 and 3 arespaced from each other by a rear wall member 4 and a front wall member 5. It

will be observed, from Figure 3 that thewall'4 has a portion ,19 thereof bent forwardly and upwardly the portion being secured to the upper edge of the wall 5 at6 (see Figure 3). A curved, deflector plate 7 ofthe shape shown in Figure 3 is' secured to the walls 2 and 8 by means of rivets 8 or the like. curved surface provided with corrugations 9. Theupper and inner edge of the plate The plate 71s curved and hasits 65 i 7 is disposed adjacent'to a gas pipe 10. It

. will be seen that the pipe 10 is spaced away, from the wall 4, thus permitting the curved I bottom of the plate 7 and the rear wall 4 to act as an air conveyor. The side walls 2 and 3 also carry a deflecting plate 11- which is sevcured to the wall 4 and terminates a spaced distance away from the wall 5. It will be seen that the-forwardlybent portion of the wall 4 and the deflector 11, diverge, and, that the ends of the member 11 terminate adjacent to openings 12' and 13 in the side walls 2 and 3, respectively, and theifor wardly bent portion of the member 4 is disposed along the upper edge of the openings 12 and 13, respectively. With this construe tion, air is drawn into the space in front of I the plate 7; and. into the space betweenthe wall 4 and the plate 7 and, when heated,

will flow up into the compartment formed by the wall 5 and the forwardly bent' por -wtion'of the member 4, and will then fiowout through the openings 12 and 13.v The side walls 2 and 3 are'further'spaced from each other by means of strips 14 and 1'5. The I' strips in turn have supporting legs 16 at tached thereto.

A ried by the walls 2 and 3, each-pipe being substantially elliptical in shape.

These pipes are disposed in the same plane and'are pair of radiator pipes 17 and 18 is car I spaced slightly from one another. It will be seen from Figure 3 thatthepipes 17 and 1 18 are placed above the forwardly bent portion 19 of the member 4 and are adapted to heat the air which flows between the. portion 19 and the pipes 17 and 18. A heating compartment 20 is carried by the wa'l'ls 2 and 3. and is'triangular in cross section. The pipes] 17 .and 18 communicate with the compartment'20 by means of pipes 21 and 22, re:

spectively The side walls 2 and 3 are also provided with openings 28 and 24 which communicate with the compartment 20. Side radiating-compartments 25 and26 are secured to the walls 2 and 3 and are divided into two prearranged air passages (see Figures 2 and 3). As shownin Figure 2, the compartment 25 has a strip 27 so disposed therein that it is adapted to convey the heated air from the opening 12 to the pipe 17 and from the pipe 18 toi-the opening 23.

The compartment 26 is provided with a strip 28 as' 'clearly shown in"Figure 3 which is adapted to' convey the air in the opening 13 to the pipe18 andfrom thje pipe 17 to the opening 24c, The air'entering-the compartment'20 by'meansof'the openings 23 and 24 is finally expelled from the device through the rear wall of the compartment 20 which has a plurality of openings 29tberein (see Figure 4)"; "Thewall's 5 19 form a heat air will be drawn into the space in front of the plate 7' and','intothespace between the plate and'the wall4. This air in turn will be heated: and will in a like manner flow through-the'openings l2 and 13. The air in thecompartment 25-which has just entered through theopening 12'- will then flow into the pipe1 7? and willadivide, partofit-going into the" compartment 20 by means of the pipe 21," andthe'other part going into the compartment 26 and thence into thecom- .partment 20' by means ofthe opening 24.

The" air in the compartment 26 which has entered 'from' the opening 13 will flow into the :pipe IS-and will then divide, part thereof going directlyinto the compartment 20 by means of the pipe 22, and the other part flowing on through the pipe 18 into the compartment' 25. andthence through the opening 24 and into the compartment 20.: It will be seen from theforegoin'g that the heated air flows in opposite directions in the device andeffe'c'tuallyheats the pipes 17 and 18', the compartments 25 and 26, and the compartmen-t 20. As heretofore stated, the heated air in the compartment is expelled through the openings 29. It is therefore'evident that the entire device acts as a radiating surface andeffectually warms the air of the room which, comes into contact therewith. In reality, this device heats the air of the room by means -of the burner pipe 10 andvalso heats the air by means of the radiating surfaces; afforded by the pipes 17 and will take a circuitous path through-said 18, the compartments 25 and 26, and the compartment 20. As clearly shown in Figures 3 and. 4, the under side of the compartment 20 lies in substantially the same plane as the portion 19. The under side of the compartment 20 and the portion 19 therefore provide an air passage which has the-walls thereof heated by the heated air passing through the device. As will be seen from Figure 3, the air of the room will enter. from the rear of the device and will flow above and belowthe pipes 17 and 18 and will flow from they device througlrthe front sides thereof.

From the foregoing it will be observed that I have provided a device in which air is caused to circulate on all sides of the members thereof. Air flowing through the radiating pipes will be effectually "dried and willbe expelled through the openings 29in a dried state so that when itcomes into contact with mirrors or the like, it will-not cause the moisture to be formed thereon, Less quantity of gas is required to heat a given sized room with this device than-is possible with a device in which the heated 0 air is not first circulatedthrough a series of" radiating-pipes. As heretofore stated, the device is simple in construction and is durable. t

I claim: v
